MACHINE FOR DRESSING AND FINISHING TILES.

SPECIFICATION forming part of Letters Patent No. 513,140, dated January 23,1894.

Application tiled November 4,1891. Serial No. 410,882. (No model.)

To all whom. it' may concern.-

Be it known that I, JOSEPH RAPP, of New Philadelphia, in the county-of Tuscarawas and State of Ohio, have invented certain new and useful Improvements in Machines for Dressing and Finishing Tiles; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which'it pertains to make and use the same.

My invention relates to improvements in machines for dressing and finishing rooting and like tiles preparatory to burning the same in the kiln; and it consists more especially in a machine that is adapted, by one operation, to sever the tile from the bar of green or plastic tiling that 'is' fed from the tile machine, punch the nail-holes, stamp the tile and cut or trimthe same to proper form.

My invention also consists in certain fea tures of construction, and in combination of parts, hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure lis a side elevation of a machine embodying my invention, showing the parts in position to receive a tile. Figs. 2 and 3 are, respectively, the former atop and the latter a bottom plan of the machine. Figs. 4, 5 and 6 are end elevations of the machine, the first being partly in section on line 4 4, Fig. 1, and showing the parts in position corresponding to Fig. l; Fig. 5 showing the parts in position ready to operate upon a tile, and Fig.6 showing the position of parts having just performed their work with the tile still in position. Fig. 7 is a vertical longitudinal section on line 7-7, Fig. 4.

A represents a suitable supporting-frame, the same being preferably made of metal, and comprising legs, A', connected by side-pieces, A2, A3, side-pieces A3 in turn being connected by one or more cross-pieces, A4, parts A A2 A3, at the respective sides of the machine, being usually integral, side-pieces A3 having depending lugsa3 constituting feet that, together with the inner lower end of legs A', are adapted to rest upon a suitable supporting-base, S. Frame A supports a plate or table, B, that in turn supports a block, C, usually of wood, block O being 'of such a contour as to conform to the shape of the tiling, T, and side-pieces A2 have respectively, 'an upwardly projecting flange, ct, for firmly clamping and holding block C in place.

The supporting-frame, at either end and on opposite sides, and preferably top and bottom, has a lug, a', projecting laterally'beyond the respective side of supporting-base S, said lugs constituting ways or guides for the depending arms or rods D of a vertically-reciprocating cross-head D. If but one series of lugs were employed, they would of course be perforated for the reciprocation therethrough of rods D', and would probably be located about midway vertically of the supporting-frame A; but I prefer the construction 'shown wherein two series of lugs are employed, top and bottom, respectively, with the lower series perforated.

Cross-head D comprises two end-pieces D2 connecting, respectively, the depending arms or rods D at the respective ends of the machine, and comprising ay central member, D2, connecting end-pieces D2, and' being preferably integral therewith.

E represents a.l block, the counterpart of block C, being preferably of wood, and being suspended from cross-head D by means of rods F, there being preferably four such rods, two at each end of the block. Members D2 ot' the cross-head have perforations of ample size to admit the free passage of rods F, and the latter are screw-threaded at their upper ends for the reception of nuts, f, that are adapted to prevent the disconnection of said rods from cross-head D. Block E, on either side, has attached a plate, G, that, as crosshead D is depressed, is adapted to engage the supporting-frame of the machine and serve as a stop to limit the depression of the block, the arrangement of parts being such that block E will just make contact with the tile below, but without a blow or undue pressure that would injure or mutilate the tile. Block E being usually of wood, and consequently quite light, to maintain the same in contact with the tile, during the succeeding operation of the machine, the block should be sufciently weighted, for instance, by a-metallic plate or disk I-l, mounted on the block in any suitable manner. Side-bars, I, connect reciprocating-rods D near the upper end of the latter, on either side of the machine, one or both of such side-bars also serving as a knifebar, having attached a cutting-blade` or knife K, according as the tile is to be cut or trimmed on one or both sides.

The mechanism for punching the nail-holes in the tile, comprises one or more punches, L,

according to the number of holes to be punched. Punches L depend from cross-head D, being preferably secured to a plate, L', in common, that in turn is rigidly secured to the cross-head.

One or more severing-wires, M, are provided, a wire M being located preferably at each end of the machine, the same being stretched tightly between the respective rods D and secured thereto, as at fm, in any suitable manner.

The stamping-mechanism comprises a longitudinal block or member, that, for cheapness and convenience in construction, is preferably made in two sections, N N', secured together for instance, by screws n, part N having secured to the face thereof, preferably by means of screws n', the stamping die N2, the latter bearing the desired words, letters, 1figures, or characters, to be stamped on the Plate or table B of supporting-frame A has a depending ear or lng, b, at either side of block N N', said ears or lugs being located diagonally opposite and having pivoted thereto, respectively, as at o, a tilting-lever O arranged laterally, the power-arm of said tilting-lever extending outside of supportingframe A, and adapted to be engaged and actuated by a depending member P of a laterally-projecting arm or lug t' of side-bar I. An ordinary screw-bolt will answer the purpose well for member P, as shown, lug or arm '1, having a hole correspondingly threaded for receiving the shank-end of said bolt, whereby member P can be adjusted vertically as required.

The weight-arm of the tilting-levers O is adapted to engage and actuate the stamping mechanism, causing die N2 to stamp the tile as desired, block C and plate or table B being slotted as at c, to accommodate the upward movement of the die, the lower portion of the walls of the slot in block C being preferably lined with metal, as shown at c', Fig. 4. Member N of the block that supports die N2, extends somewhat beyond memberN at either end, and is provided with abutment-screws or bolts Q, as shown, the shank-ends of such screws or bolts being adapted to engage the under surface of plate or table B of the supporting frame and thus limit the upward movement of the stamping die, and of course, screws or bolts Q may be adjusted to cause die N2 to make an impression heavier or lighter as desired. Blocks E and C should of course be perforated, with the perforations registering, so as to accommodate the movement of punches L, and plate or table B should be likewise perforated, as at b2, to discharge the material punched from the tile.

Plate or table B should also be slotted transversely as at b to accommodate the movement of the severing wires M, and should be extended at either end of the machine for the support of blocks C O2, that are also preferably made of wood, the upper surface of blocks C C O2 being in the same plane, and corresponding with the shape of the bar of tiling as it is fed from the tile machine (not shown), block C being adapted to receive the bar of tiling directly from the tile machine and guide the same asit is being fed to block C, and block C2 in turn guides the tile as it is fed from the machine.

The tile to be operated upon being in position on block C, the attendant or operator takes hold of the central member D3 of crosshead D, and depresses the latter until block E is arrested by means of stops G as shown in Fig. 5. A further depression of the crosshead will bring into operation severing-wires M, punches L, knives K, and cause members P to engage and actuate tilting-levers O and cause the latter to actuate the stamping-mechanism to stamp the tile, as hereinbefore described, the several parts being so arranged and adjusted relative to each other that they will performtheir respective operations with the downward movement of the cross-head as aforesaid.

It will be observed that screws or bolts Q as shown in Fig. l. The attendant or operator in a short time will acquire the ability to elevate the cross-head the proper distance, but reciprocating-rods or arms D of the crosshead are preferably provided, at their lower ends,respectively, with a stop, d, to prevent the accidental withdrawal of said rods from their lower ways or guides a.

I would remark thatI do not wish to be understood aslimiting myself to the exact construction and arrangement of parts shown, for it is apparent that modifications might be made without departing from the spirit and purpose of my invention.

What I claim is- 1. In a tile machine, the combination, with a supporting frame provided with means for holding the tile, of a reciprocatory cross-head, wires for severing the tile from the bar, stamping mechanism, and means for operating the wires and the stamping mechanism simultaneously with the descent of the cross-head, substantially as set forth.
